Shoppers who already have Target.com accounts, Cartwheel or REDcard will automatically become Target Circle members. Anyone else can sign up on or after Oct. 6 by using their phone number at any store, creating a Target.com account, or getting a REDcard.

Target's "Cartwheel" program isn't going away, according to Target Corp. It's just rolling into Target Circle. After Oct. 6, all Cartwheel deals will be found under "Target Circle offers."
